Responsibilities

Develop and maintain end-to-end RF system and link models (3GPP style link analysis, access, and feeder links), including link budgets, impairment modeling, and performance trade studies

Perform system-level simulations of digital phased array architectures and RF signal chains, and correlate against lab and field measurements

Define and flow down system performance requirements (EIRP, G/T, EVM, ACLR, NF, linearity, beam metrics) to hardware, RFIC, antenna, and firmware teams

Work with modem, waveform, and MAC/PHY teams to optimize the RF system for throughput, coverage, power, and availability across global deployment scenarios

Build reusable analysis tools and libraries (e.g., Python/Matlab/C++) to standardize link analysis and scenario sweeps across the org

Collaborate with test, calibration, and validation teams to design measurement campaigns that close the loop between models and observed performance

Support architecture reviews and program decisions with clear data visualizations, dashboards, and technical documentation

Mentor junior engineers in RF system thinking, modeling best practices, and code quality for analysis tools
